I just wrote my first e-book ever about AWK one-liners. AWK one-liners are programs that fit on one line and do one thing, such as, numbering lines, printing certain lines, finding sums, etc. The book is 50 pages long and contains 70 well explained one-liners.

I just wrote my second e-book. This time it's about sed one-liners. Sed one-liners teaches you sed, the superman of Unix stream editing, through various practical examples, such as numbering lines, printing certain lines, converting text, etc. The book is 98 pages long and contains precisely 100 well explained one-liners. Have a look!

I just finished writing my third e-book about Perl one-liners. Perl one-liners are small and awesome Perl programs that fit in a single line of code and they do one thing really well. These things include changing line spacing, numbering lines, doing calculations, converting and substituting text, deleting and printing certain lines, parsing logs, editing files in-place, and many more.
